June 30 (UPI) -- Hollywood filmmaker Ron Howard confirmed he has begun work on a Star Wars standalone adventure.

"Cool scene today but I'm afraid this is the most revealing image I dare share from my 1st day on the set of the Untitled Han Solo movie," Howard tweeted Thursday, along with a photo of his feet beside a case of water bottles.

The post came a week after Lucasfilm said co-directors Phil Lord and Chris Miller had left the Star Wars spinoff, four months into production, due to creative differences.

Despite the switch in directors, the movie is still scheduled for release May 25.

"At Lucasfilm, we believe the highest goal of each film is to delight, carrying forward the spirit of the saga that George Lucas began 40 years ago," Kathleen Kennedy, president of Lucasfilm, said in a statement announcing Howard had come onboard. "With that in mind, we're thrilled to announce that Ron Howard will step in to direct the untitled Han Solo film. We have a wonderful script, an incredible cast and crew, and the absolute commitment to make a great movie. Filming will resume the 10th of July."
